CBTG1BG Push-Pull Connector for Video Borescope Processors 2026: 1B Series 8-Contact 1 Gb/s Ethernet Connector for Industrial Inspection Equipment

The CBTG1BG-SMSM08-D72B is a CBTG1BG push-pull connector for video borescope processors — an 8-contact 1B series connector supporting 1000 Base-T4 Gigabit Ethernet transmission through four differential pairs at up to 1 Gb/s, with a 5 A rated current, low contact resistance, shielded construction and up to 5,000 mating cycles. Every specification in this guide is backed by the industrial inspection interconnect engineering of Spring Technology.

Pain point: Streaming inspection video out of an industrial video borescope processor — where the imaging module, camera head and processing unit must exchange Gigabit-class image data through a connector that also survives constant transport, cable changes and electrically noisy plant environments?

Core answer: Spring Technology supplies the CBTG1BG-SMSM08-D72B, an 8-contact 1B series connector serving as a CBTG1BG push-pull connector for video borescope processors. An industrial video borescope processor receives, processes, displays and records images captured from an inspection probe or camera, and such systems are widely used for inspecting engines, turbines, pipelines, machinery, castings and welds where direct visual inspection is difficult. The processor must handle high-speed image data while communicating with the camera or inspection probe and providing control or auxiliary interfaces, so the connector provides eight low-voltage contacts arranged as four high-speed differential pairs with 1000 Base-T4 support at up to 1 Gb/s — an architecture particularly relevant to compact Gigabit Ethernet connectivity.

2. Video Borescope Connector Design Highlights

Inspection processors move between engines, pipes and plant floors. The design advantages below explain why this CBTG1BG push-pull connector for video borescope processors suits industrial inspection equipment:

2.1 1 Gb/s High-Speed Data Transmission

  • The connector supports 1000 Base-T4 Gigabit Ethernet with four high-speed differential pairs and data transmission speeds of up to 1 Gb/s using CAT 5e cable technology. For a borescope processor, high-speed transmission matters when transferring camera images and inspection video between the imaging system and processing unit — a Gigabit-capable interface provides sufficient bandwidth for demanding digital video while keeping a compact circular connector format.

2.2 Push-Pull Locking for Fast Equipment Connection

  • Industrial inspection equipment is frequently assembled, transported and reconfigured. The push-pull self-latching system lets operators connect and disconnect the cable quickly without a threaded coupling, and the connector locks simply by being pushed into the mating receptacle — making probe or cable replacement more convenient and reducing connection time during repeated inspection operations.

2.3 Eight Contacts Integrate Multiple Functions

  • With 8 low-voltage contacts, four differential pairs can carry 1000 Base-T4 high-speed communication, letting designers use a single compact interface instead of several separate connectors. For compact inspection processors, reducing external connector count simplifies cable management and equipment integration.

2.4 Shielding Protects High-Speed Signals

  • Industrial inspection environments may contain motors, generators, power electronics and test equipment. Shielding performance specified at 75 dB at 10 MHz and 40 dB at 1 GHz helps equipment designers manage electromagnetic interference around high-speed communication interfaces — important because interference on a high-speed data link can affect communication stability and system performance.

2.5 Low Contact Resistance

  • A maximum specified electrical contact resistance of 6.1 mΩ helps maintain stable electrical performance at the connector interface, benefiting inspection equipment that needs reliable connections for both communication and auxiliary electrical functions.

2.6 Designed for Frequent Mating Cycles

  • Borescope equipment is used across multiple inspection locations and may need the probe or cable assembly connected and disconnected repeatedly. A specification of 5,000 mating cycles suits professional equipment with replaceable cables or removable probes, where durability is an important consideration.

2.7 Compact 1B Connector Size

  • The 1B size provides a relatively compact interface for professional electronic equipment. Processors must balance processing electronics, display interfaces, storage, power systems and external connections within a limited enclosure, and a compact circular connector keeps the external interface clean while retaining the mechanical advantages of a metal push-pull connector.

2.8 Mechanical Protection for Mobile Inspection Equipment

  • The chrome-plated brass housing and cable collet designed for cable fixation and bend-relief protection suit equipment that is frequently transported and handled. The connector is also specified for 100 g shock resistance and 15 g vibration resistance, adding mechanical performance for professional applications.

2.9 Wide Temperature Capability

  • The 1B connector platform specifies a temperature range of -45 °C to +125 °C, providing additional design margin for industrial inspection applications. The actual operating temperature of a complete borescope system must still be determined by the limits of the camera, electronics, cable, housing and other components rather than by the connector specification alone.
